ARNOLD GULDEMANN, OF PATERSON, NEW JERSEY.

LOOIVl-SHUTTLE.

Specification of Letters Patent.

Patented IVIar-ch 12, 1907.

Application filed April 20, 1906. Serial No. 312,839.

To all whom, it may concern:

Be it known that I, ARNOLD GU'LDEMANN, a citizen of the United States,residing in Paterson, county of Passaic, State of New Jersey, haveinvented certain new and useful Improvements in Loom-Shuttles; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, ref erence being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specific ation.

My present invention is an improvement in shuttles for broad-ware looms;and it has for its object to provide for so mounting the bobbin spindleor skewer in the shuttle as to do away with moving it on a pivot inorder to remove therefrom and place thereon the bobbins or quills.

The pivot type of mounting now in common use is objectionable forseveral reasons, among which may be mentioned the possibility of leavingthe spindle in a partlyclosed position after replenishing with theresult that the projecting end of the quill catches in the warp and doesconsiderable damage thereto and also the frequent splitting of the sidesof the shuttle caused both by the leverage action of the spindle and thefact that several securing-screws are necessary to secure the mountingin place.

My invention contemplates supporting the quill or bobbin on a spindlewhich is at least fixed. in the shuttle against pivotal movement andfrom which the quill or bobbin is removable by sliding the samelongitudinally of the shuttle off the spindle.

My invention will be found fully illustrated in the accompanyingdrawings, wherem..-

Figure 1 is a top plan view of the improved shuttle. Fig.2 is a viewshowing the spindlemounting in its left-hand end elevation, as seen inFig. 3, and the shuttle in cross-section taken in the plane of a certainscrew Z; Fig. 3 is a side view of the shuttle, the same being partlybroken away to illustrate in elevation the mounting, and Fig. 4 is aright-hand end elevation of the spindle and its mounting as seen in Fig.3.

In said drawings, a is the shuttle, having the usual bobbin or quillcavity 7), threadeyelets c, and tension device (1.

e is the bobbin or quill. f is a chamber formed as an extension of thecavity 1), and 9 two grooves opening into the same, the one in the frontand the other in the back wall of the shuttle.

h is a block having a rib t on each side and a hump or lug j on the topthereof at its front end. Preferably formed integral with this block asan axial extension thereof is a short spindle ls, which is split andsomewhat expanded, so that when the bobbin or quill is fitted onto thesame it will not slip ofi. This block is adapted to fit into the chamberf by first introducing it to the bobbin-cavity with the spindleprojecting inwardly and longitudinally of the shuttle and then slippingit back into the cavity f, the ribs 01 sliding in the grooves g. In thisposition the block is held by a screw Z, having its threaded portion madjacent its head and adapted to engage in the shuttle-wall. It will beobserved that only the head end of the screw is exposed and that,furthermore, this single screw is the only device needed and used tokeep the mounting in position.

a and 0 are two levers, whose inner ends are turned inwardly toward eachother, and

is formed with upwardly-extending parallel wings t, which receivebetween them the bottom portion of the block'h and through which andsaid block extends a pivoting-pin a. It will be observed that the pivotss and a are near the relatively opposite ends of the levers.

o is a link extending through the block and pivotally connecting thelevers r and t, and being arranged between the pivots s and u it will beobvious that if the jaw end of one lever moves outwardly the jaw end ofthe other will also move outwardly.

w is a spring coiled between the block h and the free end of lever n,being held in place by a pintle in on the latter and by a socket y, inwhich it seats in the former. This spring normally keeps the jaw closed.

The grooves Z on the under sides of the rib 1' (shown in Fig. 2) aremerely to permit the Wings 6 on the lever 0 to have free movement.

A finger depression 2 is formed in the top of the shuttle at chamber Inorder to place a quill in the shuttle, the outer end of the lever 11 ispressed on to open the jaws, whereupon the quill previously inserted inthe cavity 1) is slipped back on the spindle until the groove 1 is inoperative position to be engaged by the jaws upon the release thereof.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. The combination of a shuttle, a bobbinspindle, a mounting thereforarranged in the shuttle, pivoted bobbin-holding jaws, and a linkpivotally connected with said jaws on relatively opposite sides of theirpivots, substantially as described.

2. The combination of a shuttle having a bobbin-spindle, a mountingtherefor arranged in the shuttle, said spindle extending longitudinallyof the shuttle, bobbin-holding jaws pivoted in said mounting, and a linkpivotally connected with said jaws on relatively opposite sides of theirpivots, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of April, 1906.

ARNOLD GULDEMANN.
